Class Related

  • All Implemented Interfaces:
    VirtualMetadataConfiguration
    public class Related
extends Object
implements VirtualMetadataConfiguration
    A bean implementing the VirtualMetadataConfiguration interface to achieve the generation of Virtual metadata by traversing the path of relation specified in the config for this bean The Related bean will find the relationshiptype defined in the relationshipTypeString property on the current item and it'll use the related item from that relationship to pass it along to the virtualMetadataConfiguration property which in turn refers to another VirtualBean instance and it continues the chain until it reaches either a Concatenate or Collected bean to retrieve the values. It will then return that value through the chain again and it'll fill the values into the virtual metadata fields that are defined in the map for the first Related bean.
